What does the ecological footprint measure?
Explanation: The correct answer is A) The amount of land needed to support human activities and resource consumption. The ecological footprint is a measure of the land and resources required to support the lifestyle and consumption patterns of a population or individual. It calculates the area of land and water needed to produce the resources consumed and absorb the waste generated by human activities, taking into account factors such as food production, energy use, transportation, and waste management.
Which of the following factors does NOT contribute to an increased ecological footprint?
Explanation: The correct answer is B) Use of renewable energy sources. The use of renewable energy sources, such as solar or wind power, reduces the ecological footprint by decreasing reliance on fossil fuels and lowering carbon emissions. In contrast, factors such as high levels of consumerism, large-scale agricultural practices, and extensive transportation systems contribute to an increased ecological footprint due to their resource-intensive nature and associated environmental impacts.
Which of the following is a limitation of the ecological footprint concept?
Explanation: The correct answer is B) It only considers land usage and ignores other resources. One limitation of the ecological footprint concept is that it primarily focuses on land usage and does not comprehensively account for other important resources, such as water, minerals, and air quality. While land usage is a significant component of human impact on the environment, the ecological footprint concept could be enhanced by incorporating a broader range of resource consumption and environmental impacts.
What does an ecological footprint larger than the biocapacity indicate?
Explanation: The correct answer is B) The ecosystem is under stress and facing resource depletion. When the ecological footprint exceeds the biocapacity of an ecosystem, it indicates that the demands and resource consumption of human activities are exceeding the ecosystem's ability to regenerate and provide necessary resources. This imbalance leads to environmental degradation, resource depletion, and increased ecological vulnerability.
What is the goal of reducing the ecological footprint?
Explanation: The correct answer is A) Achieving a sustainable balance between human needs and ecological resources. The goal of reducing the ecological footprint is to establish a sustainable equilibrium between human activities and the carrying capacity of the Earth's ecosystems. By reducing resource consumption, adopting sustainable practices, and promoting conservation, it becomes possible to meet human needs while preserving the integrity and health of the natural environment for future generations.
